Los Angeles-class attack submarines regularly dock at Naval Base Point Loma, but the base gets comparatively few visits from an Ohio-class ballistic missile sub. There's one here now; the 560-foot Pennsylvania has arrived in San Diego Bay, says the Navy. The boat is one of 18 Ohio-class subs -- vessels that carry strategic thermonuclear warheads. These are the largest subs ever built for the American fleet and are capable of carrying up to 24 Trident missiles. The Pennsylvania, which is homeported at Bangor, Washington, completed a major refueling overhaul last summer.

Former President Jimmy Carter has been visiting San Diego this week. His stops included the carrier Carl Vinson, now docked at North Island. Carter served in the Navy for many years, and spent time on the crew of the Baleo-class submarine Pomfret, which then operated out of San Diego. The Pomfret was 311 feet long.
